The time for CITIC Bank to automatically adjust the credit line is not fixed. The frequency and amount of credit card adjustment are closely related to the consumption habits of credit card holders and the frequency of card use. If the banking system determines that the cardholder meets the criteria for adjusting the credit limit, it will actively increase the credit card limit for him. Generally speaking, you can take the initiative to apply for an amount increase 3-6 months after the credit card is opened. You can call the customer service phone number of CITIC Bank at 40088-95558 for consultation and application. If the application is approved, you can also apply for an increase in the amount.
